New hurricane research supports advances to NOAA’s 2022 forecasts New hurricane research supports advances to NOAA’s 2022 forecasts This summer during the 2022 Atlantic hurricane season, scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) will once again be on the frontlines helping NOAA prepare the public for severe weather. They will also conduct new research on the complex processes of how tropical cyclones form, develop, and dissipate. Read more
Greenhouse gas pollution trapped 49% more heat in 2021 than in 1990, NOAA finds Greenhouse gas pollution trapped 49% more heat in 2021 than in 1990, NOAA finds The Annual Greenhouse Gas Index serves as a measure of global society's progress - or lack of progress - in reducing greenhouse gas emissions.

Evaporative demand increase across lower 48 states means less water supplies, drier vegetation, and higher fire risk Evaporative demand increase across lower 48 states means less water supplies, drier vegetation, and higher fire risk In the western U.S., the impacts of drought conditions in the 21st century are increasingly evident as extended fire seasons, dwindling water supplies, and widespread tree mortality are becoming more common occurrences.

Study: Reducing human-caused air pollution in North America & Europe brings surprise result: more hurricanes Study: Reducing human-caused air pollution in North America & Europe brings surprise result: more hurricanes Research also finds that increased pollution in Asia may reduce tropical cyclones A new NOAA study published today in the journal Science Advances about four decades of tropical cyclones reveals the surprising result that reducing particulate air pollution in Europe and North America has contributed to an increase in the number of tropical cyclones in the North Atlantic basin and a decrease in the number of these storms in the Southern Hemisphere. The study also found that the growth of particulate pollution in Asia has contributed to fewer tropical cyclones in the western North Pacific basin. Read more
New video series explores environmental DNA New video series explores environmental DNA Have you ever wondered what animals might be present in a particular habitat or traveled through a certain area of the ocean? Scientists are able to use environmental DNA or “eDNA” sampling to help answer those questions. Read more

NOAA report highlights 2021 climate, weather, ocean research 28Mar2022 Read more The newly released 2021 NOAA Science Report includes more than 60 stories that represent a selection of NOAA’s 2021 research and development accomplishments across the range of NOAA’s mission. Read more
Study previews how climate change may alter rain-making atmospheric rivers by 2100 24Mar2022 Read more A new NOAA modeling study suggests climate change is likely to disrupt Pacific atmospheric rivers, which are important sources of snow and rain for west coast states. Read more
NOAA’s observations help EPA track emissions of a family of greenhouse gases 22Apr2022 Read more NOAA atmospheric measurements are helping to support a national inventory of emissions from an important family of greenhouse gases. Read more
Background ozone burdens Las Vegas’ air quality in spring 23Feb2022 Read more High background levels of ozone pollution make it hard for Las Vegas and other southwestern cities to meet US air quality standards in spring, two NOAA studies find. But local pollution sources drive summer's high ozone days. Read more
